CAESAR II® is a PC-based pipe stress analysis software package that is developed, marketed and sold by Intergraph CAS. This software is an engineering tool used in the mechanical design and analysis of piping systems. Use CAESAR II to create a model of the piping system
represented by simple 3D beam elements and to define the loading conditions imposed on the system.
With this input, CAESAR II produces results in the form of displacements, loads, and stresses throughout the system. Additionally, CAESAR II compares these results to limits specified by recognized codes and standards.
What are the Applications of CAESAR II
CAESAR II is most often used for the mechanical design of new piping systems. Loads,
displacements, and stresses can be estimated through analysis of the piping model in CAESAR II. CAESAR II incorporates many of the limitations placed on these systems and their attached equipment. These limits are typically specified by engineering bodies (such as the ASME B31 committees, ASME Section VIII, and the Welding Research Council) or by manufacturers of piping-related equipment (API, NEMA, or EJMA).
Hot piping systems present a unique problem to the mechanical engineer. These irregular structures experience great thermal strain that must be absorbed by the piping, supports, and attached equipment. These structures must be stiff enough to support their own weight but flexible enough to accept thermal growth.
CAESAR II is not limited to thermal analysis of piping systems. CAESAR II also has the capability of modeling and analyzing the full range of static and dynamic loads which can be imposed on the system. Because of this, CAESAR II is not only a tool for new design. It is also valuable in troubleshooting or redesigning existing systems. You can determine the cause of failure or evaluate the severity of unanticipated operating conditions such as fluid to piping interaction or mechanical vibration caused by rotating equipment.
Why is CAESAR II from other Pipe Stress Software
Our staff of experienced pipe stress engineers are involved in day-to-day software development, program support, and training. This approach has produced software that most closely fits the requirements of today‘s pipe stress industry. Data entry is simple and straight-forward through dialog boxes. CAESAR II provides the widest range of modeling and analysis capabilities without becoming too complicated for simple system analysis. You can tailor your CAESAR II installation through default settings and customized databases. Comprehensive input graphics confirm the model construction before the analysis is made. The software's interactive output processor presents results on the monitor for quick review or sends complete reports to a file or printer. CAESAR II uses standard analysis guidelines and provides the latest recognized opinions for these analyses.
CAESAR II also offers seamless interaction with Intergraph® CADWorx® Plant, which is an AutoCAD®-based design and drafting system for creating orthographic, isometric, and 3D piping drawings. The two-way-link automatically generates stress analysis models of piping layouts or creates spectacular stress isometrics in minutes from CAESAR II models.
CAESAR II is a field-proven engineering analysis program. It is a widely recognized product with a large customer base and an excellent support and development record.

Software Revision Procedures
CAESAR II is updated continually to reflect engineering code addenda, operational
enhancements, your requests, operating system modifications, and corrections. New versions are planned and targeted for a specific release date. However, there may be corrections necessary to the current version before the next version can be released. When this occurs, a correction to the current version is made. This correction is referred to as a "build."
A build is finalized, announced, and posted to the web site. All maintenance builds for new releases contain all previous builds. This increases the download size and time required to obtain the build, but only one build is required at any given time.
Identifying Builds
When posted on the web site, builds are identified with the program identifier and the date the build was generated, as in C2YYY-YYMMDD.exe.
Can Builds be Applied to Any Version?
No. As new versions are released, additional input items become necessary and must be stored in the software data files. In addition, file formats and databases change. A build is intended for one specific version of the software. Using a build on a different version without specific advice from Intergraph CAS Support is a sure way to cripple the software.
Obtaining Builds
Builds are available for download at our website (http://www.coade.com) and are arranged in sub-folders by program. Each file contained in the folder includes a description , its size, and the creation date.
What is Contained in a Specific Build?
Each build contains a file named BUILD.TXT containing a description of all corrections and enhancements in the current build. When necessary, additional usage instructions can be found in this file.
Installing Builds
Builds distributed for Windows-based applications use a Windows installation procedure with a standard SETUP.EXE program to actually install the build. This procedure ensures that the necessary files are registered with the system and that the uninstall utility can perform its task.
24
CAESAR II User's Guide
Detecting/Checking Builds
When a build is ready to be released, Help > About CAESAR II is revised to reflect the build level. To see which program modules have been modified, you can run an Intergraph CAS utility program from within the program folder.
Diagnostics > Build Version scans each of the .EXE modules in the program folder and lists
the size, memory requirements, and build level for each file. A sample display from this utility is shown below.
Archiving and Reinstalling an Older, Patched Version
When a new version of the software is released, what should be done with the old, existing version? The distribution disks sent from Intergraph CAS should be saved. Additionally, any builds obtained should be archived. This allows full usage of this version at some later time, if it becomes necessary.
To reinstall an older version of the software, first install the software from the Intergraph CAS CDs. Then, install the latest build. Each build includes the modifications made in all prior builds.

Updates and License Types
You can identify CAESAR II update sets by their version number. The current release is Version 2013 R1 (6.10). Intergraph CAS schedules and distributes these updates periodically,
depending on their scope and necessity. The type of CAESAR II license that you have determines whether you receive these updates. There are three types of CAESAR II licenses:
Full Run - Provides unlimited access to CAESAR II. Updates, maintenance, and support are
available on an annual basis.
Lease - Provides unlimited access to CAESAR II with updates, maintenance, and support
provided as long as the lease is in effect.
Limited Run - Provides 50 static or dynamic analyses of piping system models over an
unlimited period of time, but does not include program updates. Your license is upgraded, if necessary, whenever you purchase a new set of 50 runs.
Intergraph CAS only ships the current version of CAESAR II, no matter which type of license you purchase. Updates will be delivered on request to lease users and to full run users who have a current support/maintenance contract.

The Piping Input window displays.
You can use Input > Piping to activate the Piping Input window.
Piping Input generation
Model input generation consists of describing the piping elements and any external influences (boundary conditions or loads) acting on those elements. Two node numbers identify each pipe element end. Every pipe element also requires the specification of geometric, cross sectional, and material data. One method of data entry is the Piping Spreadsheet.
You define a piping element on its own spreadsheet. Some data, when defined on a piping element, is automatically duplicated by CAESAR II to subsequent piping spreadsheets. This means that for many elements you only have to confirm the node numbers and enter the delta-dimensions, and then CAESAR II automatically duplicates from the previous element the other data such as pipe diameter, operating temperatures, material type, and so forth. You can always enter specific data to override the duplicated data in the piping spreadsheet for an element.
The menus, toolbars, and accelerators offer a number of additional commands to enter auxiliary processors or use special modelers or databases. The commands and general input instructions of the piping spreadsheet are discussed in detail in Piping Input Reference (on page 89).
1. In the DX box, type 10-0 (which is 10 ft). 2. In the Diameter box, type 8 (8-in. nominal).
CAESAR II automatically converts this value to the actual diameter. 3. In the Wt/Sch box, type S (standard schedule pipe wall).
CAESAR II automatically converts this to wall thickness. 4. In the Temp 1 box, type 600 (degrees Fahrenheit). 5. In the Pressure 1 box, type 150 (psig).
6. Double-click the Bend check box. The Bends tab displays.

CAESAR II User's Guide
The piping input preprocessor has an interactive graphics and a list view function to make model editing and verification easier. You can verify your model using the Graphics or List utilities, although a combination of both modes is recommended. By default, the graphics screen
displays to the right of the input spreadsheet. You can click the small pin in the upper-left corner to collapse the input spreadsheet to provide maximum graphic space.
Model Error Checking
When you are finished modeling, you must run File > Error Check before you can run an analysis.
The two main functions of this error check are to verify your input data by checking each individual piping element for consistency and to build the execution data files used by the analysis and review processes.
Errors that will prevent the analysis from running (such as a corrosion allowance greater than the wall thickness) are flagged as fatal errors and display in red text. Unusual items (such as a change of direction without a bend or intersection) are flagged as warnings and display in green text. Other informational messages that may show intermediate calculations or general notes display in blue text. All messages display in the Errors and Warnings tab next to the model graphics.
When you double-click an error or warning message, CAESAR II displays the spreadsheet of the associated element and highlights the element in the graphic display. You can sort error
CAESAR II User's Guide
33
messages by clicking the column titles. Use File > Print to print the entire error report or selected sections. Use the options arrow on the Error Check icon to display only fatal errors or all errors.
If there is a fatal error, you must return to the input module to make corrections. Click the
Classic Piping Input tab or double-click the row number for the error message.
If the error check process completes without fatal errors, a center of gravity report displays, the analysis data files are generated, and the solution phase can commence. If fatal errors do exist, the analysis data files are not generated and the solution phase cannot begin. You must make corrections and rerun the Error Checker until successful before analysis is permitted.
Building Load Cases
After the analysis data files have been created by the error checker, you can run a static
analysis. The first step of a static analysis is to define the load cases. For new jobs (there are no previous solution files available), the static analysis module recommends load cases to you based on the load types encountered in the input file. These recommended load cases are usually sufficient to satisfy the piping code requirements for the Sustained and Expansion load cases. If the recommended load cases are not satisfactory, you can modify them.
1. From the Piping Input window, select Edit > Edit Static Load Cases . The Static Analysis dialog box displays.
2. You can build loads two ways:
Combine the load components defined in the input (weight, displacements, thermal cases, and so forth) into load cases (basic cases), or
Combine pre-existing load cases into new load cases (combination cases).
3. Build the basic cases by selecting one or more load components in the Loads Defined in
Input list and then dragging and dropping them to the Load Cases list to the right. You can
also type on any of the individual load case lines. Stress types (indicating which code equations should be used to calculate and check the stresses) are selected from the Stress
Type list.
Combination cases, if needed, must follow the basic cases. You can build combination cases by selecting one or more load components and the dragging and dropping the basic load cases from earlier in the load case list to combine cases (or blank load cases) later in the list.
You can have a maximum of 999 static load cases. For more information, see Static Analysis Dialog Box (on page 456).
Run a static analysis
After the load cases are defined, you can run the analysis.
1. Select File > Batch Run to run the actual finite element solution.
The analysis creates the element stiffness matrices and load vectors and solves for displacements, forces and moments, reactions, and stresses. The analysis also performs the design and selection of spring hangers and iterative stiffness matrix modifications for nonlinear restraints. Finally, the Static Output Processor window displays.
Static Output Review
When the analysis is finished, you can review the results using the Static Output Processor window.
34
CAESAR II User's Guide
1. On the main CAESAR II window, select Output > Static. The Static Output Processor window displays.
2. In the Load Case Analyzed list, select one or more load cases for which to review results. 3. In the Standard Reports list, select one or more reports to review.
4. Click --> Add.
5. Select where you want to view the results: the screen, Microsoft Word or Excel, the printer, or an ASCII file.
6. Click Finish to view the reports.
7. Click Options > Graphical Output to review the analytic results in graphics mode, which can produce displaced shapes, stress distributions, and restraint actions.
The actual study of the results depends on the purpose of each load case and the reason for the analysis. Usually the review checks that the system stresses are below their allowables,
restraint loads are acceptable, and displacements are not excessive. Additional post processing (such as equipment, nozzle, and structural steel checks) might be required depending on the model and type of analysis.
After you finish reviewing the output, return to the main window by exiting the output review module.
